RE: H-2017-0131 ROCKBURY SUBDIVISION
The Idaho Transportation Department (ITD) has reviewed the referenced final plat application by
Rock Harbor Church, Inc for Rockbury Subdivision consisting of 1 commercial lot, 1 residential lot,
and 3 common lots located on a parcel north of US-20/26 (West Chinden Boulevard) milepost 35.64.
ITD has the following comments:
1. The parcel abuts the State Highway system.
2. The applicant has provided a Traffic Impact Study (TIS) which was completed for a previous
development plat designed on the same parcel. Based on ITD review of the provided
documents it was found that the TIS that was submitted does not accurately reflect the
proposed land use for the new proposed plat. ITD requests that a TIS be completed using the
correct land uses for the development.
3. ITD has concerns that storage space for northbound left turn movements from Tree Farm Way
onto Tree Haven Way is not adequate for the volume of traffic that will be generated by the
proposed development. Traffic stacking in that location could cause vehicles to block the
westbound through lane of US-20/26. ITD requests that the turning movements and storage
capacity be verified for that movement.
4. No access to the State Highway system is approved with this application. Applicant initially
submitted an ITD Right-of-Way Encroachment Application and Permit- Approaches or Public
Streets (ITD Form 2109) for an access point at US-20/26 milepost 35.51 LT, but subsequently
withdrew their application. The access point at US-20/26 milepost 35.51 LT may be allowed as
temporary if a traffic impact study supports its installation. Connection to or modification of an
existing access to the State Highway system will require a permit from ITD.
5. ITD has completed a corridor study of US-20/26. The corridor study shows the future corridor
width will need to be 200 feet wide. It is unclear from the submitted documents if the applicant
has taken this into consideration and left sufficient clear area to avoid impacts to buildings and
any greenspace that may be required by the City of Meridian. A view of the corridor study plan
for this area can be found at:
http://apps.itd.idaho.gov/apps/us2026CorridorStudy/Strip-Maps.pdf . Included below is a view
of the typical section:
6. The City is reminded that the US-20/26 corridor is already congested. This project will
increase the number of vehicle trips in the corridor. ITD has no current funding assigned to
mitigate traffic congestion in the US-20/26 corridor in this area.
7. IDAPA 39.03.60 governs advertising along the State highway system. The applicant may
contact Justin Pond, Program Manager for ITD’s Headquarters Right-of-Way Section at 334-
8832 for more information.
8. Idaho Code 40-1910 does not allow advertising within the right-of-way of any State highway.
9. At this time ITD is reserving comment on the Final Plat application until after the traffic
impact study has been submitted and reviewed as access changes may be required.
If you have any questions, you may contact Shona Tonkin at 334-8341 or me at 332-7190.
Sincerely,
Ken Couch
